REC Silicon Restart of REC Silicon Moses Lake Update

Moses Lake, Washington USA -- November 30, 2023: REC Silicon ASA provides an
update on the successful restart of the silane-based high-purity granular
production facility in Moses Lake, Washington.

As stated in the Q3 2023 release, the start-up process commenced in late
October and early November for the initial systems required to begin ramping
up our production process. Consistent with prior communication, our Silane III
unit came online, and production of the first granular polysilicon has
started. We will continue to bring capacity and capability online, as we
stabilize each step and phase of our ramp, which is still targeted to result
in full capacity of granular polysilicon available in Q4 2024.

Further planning is currently underway to evaluate opportunities to pull
forward the scheduling and pace of the previously communicated ramp while
maintaining stability and focusing on continuous improvement of our
high-purity granular product.

Kurt Levens, CEO, said, "Our focus is on stability and increasing capacity
utilization as soon as practical. Our employees' experience in starting up and
operating complex continuous chemical processes meshed with continuous
polysilicon processes is directly indicated in where we are right now. As
previously communicated, we plan to start the first deliveries of high-purity
granular polysilicon in Q1 2024, and we look forward to presenting further
information in person during our Quarterly Results update in February."

As a leading producer of silane gases and silicon metals, REC Silicon is
well-positioned to capitalize on the global megatrends of digitalization,
energy transition, and energy storage. The company has developed a strong
market position in the Semiconductor industry based on its operations in
Butte. The re-opening of the Moses Lake operations will enable REC Silicon to
provide polysilicon to an emerging US solar value chain and potentially supply
silane gas for anode material to a fast-growing battery industry.
